The 26-year-old opted for The Desired Cocktail Midi Dress ($420), featuring Shona Joy’s exclusively designed lace with sheer panels, plus a plunging neckline and spaghetti straps, taking the piece’s sex appeal right off the richter scale.

She styled the LBD safely with black pointed-toe heels and a sizeable envelope clutch, as well as fine-gold and diamond rings and jagged drop earrings. The actress brought it all together with side-swept waves, dark eyelids and navy-blue nail polish, bringing an understated elegance to an otherwise seductive look.
